Set-up in the bay

The set up of my cages will be constricted to the north end of the bay. I do not want to set the cages up in multiple areas of the bay. If I did, I would introduce another variable to the data, as goby numbers will vary slightly across the bay. With the limited number of cages that I have, I want to have the best statistical chance of showing a difference.

Thus, set-up in the bay will be two rows of cages, each row will have 3 cages. Thus, there will be a total of 6 cages. They will be placed 15 feet away from each other.
